VETERINARY FLOAT.

Specification of Letters Patent. Patented July 27, 1920.

Application led April 3, 1920. Serial No.`371,158.

T 0 all 'whom it may concern.'

Be it known that I, HAROLD M. Baix, Va citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Veterinary Floats, of which thefollowing is a specification.

The present invention relates to a veterinary float, and will be fullyunderstood from the following description illustrated by 'theaccompanying drawings, in which- Figure 1 is a plan view of the float,partially broken away, with the float section upwardly 5 Fig. 2 is aback view of the head or holder of thetloat;

Fig. 3 is a broken longitudinal section through the head of the iioat;

Fie'. 4 is a transverse section on the' line 4 of :Fig 3, viewed in thedirection of the arrow; and

Fig. 5 is a transverse section on the line 5 of Fig. 3, viewed in thedirection of the arrow.

Referring more particularly to the drawings the numeral 10 indicates therasp section of the float, which is retained in position in achannel-like support or holder cornprising a back 12 and side members13, 13, each of which is provided with an overhanging edge or lip 14,14, which engages the upper surface of the rasp section 10, at or nearits edge. Gn the back of the holder 11, at one end is formed anenlargement which is provided with a socket 16 passing longitudinallyinto the enlarged portion 15, and a second socket 17 passingperpendicularly from the upper surface of the back 12 of holder 11 intothe enlargement 15. A threaded bore 18 passes from the socket 16 to thesocket 17.

.The handle bar or rod 19 is provided at one end with a cylindricalportion 2O which fits into the socket 16, and as an extension of this athreaded portion 2l adapted to mate with the threads of the bore oropening 18. The end of the threaded prolongation 21 of the handle 19 isof conical formation, as indicated by numeral 22, and enters a conicalopening of larger diameter, but preferably of the same angle, formed inthe pin 23, which is slidably tted into the bore 17. To prevent this pinfrom falling out of the holder it is provided on one side with a groove24 which does not extend. to the lower end of the pin, and a fasteningpin 25 is forced through a suitable bore drilled i in the enlargedportion 15 on the back of the iioat until it enters the said groove 24.

In operation of the device a rasp section 10 is placed in thechannel-like holder of the float, the handle being then partiallyunscrewed, the pin 23 thereby being permitted to move downwardly intothe socket 17. The rasp being in position, the handle 19 is screwedtight, its conical end 22 thereby entering the conical opening in thepin 23 and by its forward movement wedging the latter out of the socket17 and into firm engagement with the lower side of the rasp. The edgesVof the upper surface of the rasp are thereby forced into engagement withthe overhanging ledge 14 of the holder, and the rasp is thereby securelyheld in position.

to engage its upper surface, a handle for said holder', a pin looselymounted in the back portion of the handle, and means operable onrotation of the handle in one direction to force said pin against thelower section of the rasp section and thereby wedge the latter againstthe overhanging .members of the holder and when rotated in the oppositevdirection to permit the pin to fall out of contact with said raspsection.

2. In a veterinary float, a rasp section, a holder therefor providedwith a channel for receiving the rasp section, a pin slidably secured inthe holder and adapted to engage and secure the rasp section in theholder when moved outwardly, said pin being provided with aconicalcavity on one side, and a groove on its opposite side extending aportion of its length, a second pin having end engagement with saidgroove to retain said iirst-named pin in the holder, a handle for saidholder and screw-threaded thereinto, said handle being provided with aconical` end adapted to enter the conical cavity in the pin, whereby onrotation of the handle in one direction it wedges the pin K outwardlyand on rotation in the other di-l HAROLD M. BRIX.
